im doing a homestuck reread because its been so long since i last dived in that i feel like its worth going back to read and see what i get out of it this time.
anyways im sure that with the number of people doing homestuck textual analysis out there somebody's already noticed this and had more interesting things to say about it but i DO think its interesting that dave is essentially a tutorial character for john+the readers early on (this is a snippet from their second ever pesterlog)
like you have dave telling john how very basic aspects of his inventory system works. obviously this is narratively useful at this point to tell the readers (who were literally inputting commands for what to do next) how the systems work, and its also common to express world-building and exposition via character dialogue.
but its also interesting that dave later splits into davesprite, who is literally a game construct that comes with some tutorial information programmed in for the Literal in universe game of Sburb.
something something metatextual layers blah blah unintentional foreshadowing. idk what it means i just think is a neat lil parallel.
